Stereo Satellite Elevation Surveying: Ghadames, Libya
From August to November of 2010 PhotoSat produced a 3,962 km² 1m survey grid from 50cm WorldView-2 stereo satellite photos for a project in Ghadames, Libya. The client hoped that by utilizing stereo satellite elevations during and after a highly accurate seismic survey they could improve the efficiency of their project. The stereo satellite elevation surveying was initially referenced to 19 ground survey targets and [...]
Volumetrics at Suncor’s Oil Sands Mines
The vast oil sands deposits of Northern Alberta contain over 1.5 trillion barrels of oil making them one of the world’s largest hydrocarbon reserves. Of this total resource more than 160 billion barrels can be economically produced with current technology. This is sufficient to meet total North American oil requirements for more than 20 years at current consumption rates. The need for a cost-effective mapping strategy [...]
What mapping and surveying accuracy do I need for my mining exploration project?
By Gerry Mitchell, P.Geo, President PhotoSat GPS survey of a PhotoSat survey ground control point. Accurate topographic mapping and surveying of a mining exploration project requires a significant investment of time and resources. For early stage mining exploration project work, 3m survey accuracy is sufficient. Early stage mining exploration project work: Geological mapping and outcrop sampling Geochemical surveys Geophysical [...]
Majnoon Case History
Accurate topographic mapping and surveying of a mining exploration project requires a significant investment of time and resources. For early stage mining exploration project work, 3m survey accuracy is sufficient. Early stage mining exploration project work: Geological mapping and outcrop sampling Geochemical surveys Geophysical surveys: magnetics, electromagnetics, induced polarization, gravity Most early stage mining exploration projects require mapping quality topography, accurate to [...]

The spark that ignited the PhotoSat accuracy studies
[mp_row] [mp_span col="12"] 2016 PhotoSat WorldView-3 satellite surveying accuracy study, Asmara, Eritrea. “Everything that the last speaker just told you is wrong”. This shocked me since I was the last speaker. I was just rejoining the audience after my presentation at a satellite data distributors’ conference in San Diego in 2008. I had given a presentation on PhotoSat’s experience using [...]
